69 Camaro need help deciding suspension

[coachwinbush]

I have a 69 Camaro that I am building I have stock subframe with dse tublars qa1 coil overs but was thinking about doing the shockwAves. Another option is the speed tech full frame because I can use my brakes that I have already purchased and also there torque arm. Thirdly the dse Detroit speed hydroform and quadralink. Could use some help why which is better and which is better for resale value purposes
thanks
